Just like humans, dogs can have allergies to food and some of the symptoms can give you a clue that your dog has an allergy. Skin infections, itching around the face, ear infections, an itching belly and chewing of limbs can all be signs of a food allergy.
Unfortunately, commercially manufactured dog food that most of us feed our dog is the cause of many food allergies in dogs. The proteins, fillers and colorings present in these foods are largely responsible, and store bought dog food can lead to allergies in many dogs. The most commonly affected parts of your dog are the GI tract and the skin.
Unusual behavior, such as scratching after eating can often be a sign of allergies to food, and it is the responsibility of every dog owner to be aware of these signs. Scratching can also be a sign of a fungal infection or other condition.
Corn and wheat allergies are common in dogs, although there can be a big difference in the reaction level. You can get a fairly accurate idea of what your dog is eating by making a point of always checking the ingredients on the label. Try to avoid foods that contain a lot of food coloring.
Food allergies in dogs can also lead to excessively restless behavior or hyperactivity. Allergies can also be brought on by the preservatives and high levels of fat present in some store bought dog food brands. If in doubt, always read the label carefully before buying any dog food or feeding it to your dog; you may need to consult your vet if you feel you need further advice on what to feed him.
It can often be hard to accurately diagnose a food allergy, as some of the symptoms described above may be indications of other issues, such as problems with the digestive system. To determine of it actually is your dog’s food that is responsible for any issues, keep an eye on your dog’s behavior before, during and after feeding. Check the ingredients listed on the label and see if there are any connections with their symptoms.
